Cycle path along the Cologne–Aachen high-speed rail line near Manheim

On both sections together, you drive about 6.6 km on the finest wide asphalt without traffic on the way. The freeway runs parallel and brings with it a certain level of noise. So just shut up :-). The path is great to drive, does not require any special skills and is therefore fully recommended.

Between the highway and the railway. Well paved

Here, you can compare the "bicycle highway" to the "highway" and the "ICE train line." It's an opportunity to "rev up" for about 6-10 kilometers and get your speed and sweat on for a completely flat stretch. I personally recommend visiting the gas station near Buir, near the train station/malt factory (heading south, pass under the railway)—they make fresh, inexpensive rolls.
